New AT&T Telepresence Solution® Features Enable Improved
Connectivity and Interoperability

DALLAS, July 31, 2012 – As more video applications and
hardware become embedded in personal devices such as laptops and tablets,
AT&T is taking the next step toward making video conferencing as easy and
as seamless as making a phone call. AT&T announced today the expansion of
video features and on-demand meeting capabilities that can help facilitate
broader video collaboration through AT&T
Telepresence Solution®.

By eliminating the need to reserve video resources in advance, AT&T
Telepresence Solution customers can easily conduct meetings and instantly
connect face-to-face through video with partners and colleagues regardless of
whether or not they are registered on the AT&T Business Exchange. These new
features include:

Guest Access Enhancements – Users with single screen
endpoints can now join scheduled meetings from a corporate VPN
or the Internet by dialling into the AT&T Business Exchange.

Virtual Meeting Rooms – Users can hold meetings without
advanced reservations over a variety of networks through an expanded universe
of endpoints including tablets, desktops, conference and immersive rooms.
Participants can simply dial a number and enter an access code to start a
meeting.

Using these features, customers can join meetings over the internet from
desktop/laptop and select mobile devices using video applications like the
Cisco Jabber™ Video for TelePresence; Polycom® RealPresence® Mobile; LifeSize®
ClearSea™ from Logitech, and other standards based video clients using WiFi hot spots, 3G, 4G
and 4G/LTE wireless connections (where available). These new features add even
more flexibility for customers to meet over video, from more devices and over
more connections, virtually anywhere and at anytime.

“These new AT&T Telepresence Solution enhancements help make video
conferencing more useful,” said Brian Washburn, Research Director, Network
Services, Current Analysis. “These features cut across different video devices,
vendors, and calls types to bring ease and simplicity to the end user
experience.”

With the telepresence systems market expected to grow at 25.7% per year
through 20131, AT&T continues to pursue strategic initiatives to
expand global reach, reliability, and flexibility by giving customers a wider
range of vendors to choose from. Additional enhancements include:

Expanded video-as-a-service capabilities – AT&T is
expanding its hosted call control capabilities to include a comprehensive range
of Polycom® RealPresence® video solutions, from desktop to conference room to
immersive theater solutions as well as a complete line of Cisco video
endpoints. This means the equipment needed to schedule, initiate, control,
manage and bridge together the various endpoints is hosted in the AT&T
network. This simplified approach can help customers avoid deploying and
maintaining their own infrastructure equipment.

Additional service bundles – AT&T also announces fully
managed service bundle availability of a broader range of endpoints, including
the popular Cisco Telepresence® TX9000 Series, becoming one of the first
Cisco-certified managed services provider to support this new immersive
endpoint globally.

Greater telepresence interoperability – AT&T is the
first service provider to support Polycom® HDX® desktop and conference room
solutions, and Polycom® OTX™ and RPX™ immersive theater systems implementing
Telepresence Interoperability Protocol (TIP) to enable native single and
multi-screen interoperability with one or three screens between telepresence
endpoints from Cisco and Polycom. This interoperability supports direct dial as
well as both scheduled and reservation-less multipoint calls (virtual meeting
rooms) on the AT&T Business Exchange along with presentation and data
sharing.

Expanded global availability – AT&T can now provide
service in 80 countries and, with the recent addition of the Philippines and
Malaysia, now offers fully managed service bundles in 40 of those
countries.

“AT&T is invested in providing enhanced video services without borders,”
said Alan Benway, Executive Director of AT&T Telepresence Solution,
AT&T Business and Home Solutions “AT&T customers have the freedom to
choose from the broadest set of endpoints and the freedom to meet at the time
that best suits them while leveraging their immersive rooms, group systems, mobile
devices, laptops, or desktops.”
